Paul, N1BUG, recently conducted some tests alternating transmissions of JT9-1 and JT9-2 on 2200m. This was possible as recent releases of the slow JT9 software have been more stable, thanks to the continued efforts of the author. I participated in…

Paul, N1BUG, announced on the evening of 4th December 2018 that he would be transmitting DFCW60 on 137.779 kHz overnight. This provided an opportunity to experiment with the Argo software by I2PHD. The KiwiSDR was tuned to 136.000 kHz and…

The polar path opened Sunday 2 December 2018 permitting reception of VE7SL from British Columbia, Canada, for the first time. The use of higher power and shorter transmit/receive periods with JT9 is allowing short openings over difficult paths to materialise,…

Many LF/MF operators have downloaded and tried ON7YD’s slow JT9 software in the last few weeks, with varying degrees of success. The software would benefit from further development, which I hope the author is able to accomplish given the high…

Yesterday I purchased a used Wellbrook Loop for future installation at a remote location. There was a small problem with the 12v power injector, which was quickly rectified. Installed at home for testing, the signals were weaker compared to the…

Rik has released software, derived from elements of WSJT-X, which enables communications using the slower JT9 modes – specifically JT9-2 (2 minute periods) and JT9-5 (5 minute periods). Software available here (Windows): SlowJT9 The only mode of JT9 currently supported…

Four WSPR transmissions from N1BUG were decoded early this morning, using the Wellbrook Loop and KiwiSDR receiver. Transatlantic communication on 630m is difficult – 2200m even more so. In the light of the promising reception results, I will leave the…

Observing activity on 17,15,12 and 10m on Sunday 14th October 2018 it is clear how transformative FT8 has been on these bands compared to what activity may have found in previous years at this part of the cycle. The wideband…
